- Specification of Letters Patent.

Patented April 14, 19Q8.

Application filed J'ime 5, 1906. Serial No. 320,338;

To all whom it may concern;

Be it known that I, CHARLES H. 'BACH, a citizen of the United States,residing at Red Lake, State of Minnesota, have invented certain new anduseful Improvements in Composition for Matches and Stoppers; and I dohereby declare the following to be a full, clear, and exact descri tionof the invention, such as will enable otiiers skilled in the art towhich it appertains to make and use the same.

his invention has relation to a'newcomposition of matter that is.adapted for the manufacture of matches; and it is the object of theinvention to rovide the said new composition of matter in bulk,andsupply it in this form to manufacturers, to be made into matches orother articles to which it may be suited.

It is my purpose, also, to furnish the'said new com osition of matter indifferent modified con itions, where called for, that is in a conditionhaving greater or less specific gravity in one of its ingredients.

The nature of the invention is embodied in a composition of'mattercomposed, of wood charcoal and macerated or ground fibrous material,forming pulp suitable for the manufacture of paper. These substances arecompletely intermixed so that they constitute to allintents and purposesa unitary substance consisting of from one-tenth to three-eighths of onepart of wood charcoal to one art of pulp, for matches'for common 'use, te pro-. portions being varied in quantity as it may be esired to, havethe" match burn slowly or quickly. Again, the charcoal may vary inspecific gravity for the reasons stated, it being knownthat charcoalroduced from hard woods is of different s eci c gravit and burns fromsoft moreslowl than t at roduce woods, the atter having ess specificgravity and burning much more freely than the former.

' fitted, I avail myself of the variation in spe- In addition to varyingthe proportions of the differences in specific gravity of theconstituent elements composing the substances that enter into my newcomposition of matter,.I add to it various other substances ascircumstances and conditions may demand charcoal and pulp and takingadvantage of v A to render it useful. For example, a binder, 1n thenature of a gum or resinous matter 1n- .termixed with the matter tocause the particles to adhere and speedily solidify Lathe extent ofhaving them take perm anent form, so that the composition can be wroughtinto matches as articles of. manufacture.

As examples, if I propose 'to use my new composition of matter in themanufacture of friction matches, to which it is peculiarly cific gravityof wood charcoals and em 0y one-twentieth part of charcoal made rom 1n,piiped fibrous material, in the proportions substantially as specified,completely intermixed, andcombined with a resinous binder;

In testimony whereof, I affix my signature, in presence of twowitnesses.

CHARLES H. BACH.
